Billionaire Elon Musk, who offered up a miniature submarine to rescue the soccer team trapped in a flooded cave in Thailand, responded to a question on Twitter about the Flint, Michigan water crisis. Musk said he was willing to help fund a solution.

Flint long ago fell into an economic depression, along with Detroit, after the collapse of the auto industry. Flint was dealt another blow in recent years when it was found the city used lead pipes for its water system.

Rick Snyder, Michigan’s governor, recently stopped Flint’s free bottled water program, but citizens still do not trust the water’s safety, considering the city continues to use lead pipes.

Now, Musk is saying on Twitter that he will fund water filters for anyone who needs one.

This tweet from Baby D set the plan in motion.

Hey @elonmusk I heard a bunch of people saying there's NO WAY you could help get clean water to Flint, Michigan. Said you wouldn't be capable idk
